Actually, this is completely unrelated. The deep stall is an event that occurs after the aircraft stalls, something you will never see in normal operations.
The reason why the CRJ and the Dash-8 have more of a noze down attitude compared to a Boeing or an Airbus has to do with the type of airfoil (wing cross section shape), the wing incidence (angle at which the wing is attached to the fuselage), the flap system and different "downwash" (the angle of the airflow behind the wing) that affects T-tail and low tails in a different way. So there are many factors playing there, but deep stall is not one of them.
